VIQUA Lamp and Quartz Sleeve ReplacementModels: D4, E4, F4, D4 Premium, Plus ModelsDiscontinued Models: A, B, C, D, E, F, B4, C4

Overview UV Lamp replacement: The amount of UV light created by the UV lamp decreases over time, requiring that the UV lamp be replaced. The system will automatically notify you when it is time to replace the UV lamp.

Lamp Sleeve replacement/maintenance: Minerals in the water slowly form a coating on the quartz sleeve. This coating must be removed because it reduces the amount of UV light reaching the water, thereby reducing disinfection performance. If the lamp sleeve can not be cleaned, it must be replaced.

Section 2 Maintenance

WA R N I N GFailure to follow these instructions could result in serious injury or death.

UV Light Hazard

• ALWAYS use UV protective gear, including gloves and UV safety glasses.

• NEVER look directly at illuminated UV lamp, even when using protective gear.

• NEVER illuminate UV lamp outside of the UV chamber.

• If accidental exposure occurs, immediately cool affected area and consult physician.

Contamination Hazard

• If UV lamp breaks, avoid inhalation, ingestion, or exposure to eyes and skin. Wear appropriate clothing and personal protective equipment.

• NEVER use a vacuum cleaner to clean up broken UV lamps as this will scatter the mercury. Obey local regulations and guidelines for the removal and disposal of mercury waste.

C A U T I O NFailure to follow these instructions could result in minor or moderate injury.

Thermal Hazard

• Allow UV lamps, UV chamber to cool for a minimum of 10 (ten) minutes before handling.

• When there is no water flow, the water in the chamber will become hot. To prevent scalding, allow the system to cool for 10 minutes before draining the system.

Personal Injury Hazard

• UV lamps and lamp sleeves are fragile. Do not strike, bend or apply pressure, or they will break.

• DO NOT handle UV lamps or lamp sleeves with bare hands. Wear rubber or latex gloves to handle previously installed UV lamps and soiled lamp sleeves to protect against contaminants. Wear cotton gloves to handle new UV lamps and clean lamp sleeves.

Hg Exposure

• The UV lamp contains mercury. If the lamp breaks, then avoid inhalation or ingestion of the debris and avoid exposure to eyes and skin. Never use a vacuum cleaner to clean up a broken lamp as this may scatter the spilled mercury. Obey local regulations and guidelines for the removal and disposal of mercury waste.

N O T I C ESystem Protection

• To protect the Controller, a UL 1449 certified (or equivalent) transient voltage surge suppressor is strongly recommended.

Avoid Injury

• Read and understand this Instruction Sheet before operating and performing any maintenance on this equipment.

Warning: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

WA R N I N G • Always disconnect power before performing any work on the disinfection system. • Always shut-off water flow and release water pressure before servicing. • Regularly inspect your disinfection system to ensure that the power indicators are on and no alarms are present. • Replace the UV lamp annually (or biennially if seasonal home use) to ensure maximum disinfection. • Always drain the chamber when closing a seasonal home or leaving the unit in an area subject to freezing temperatures. • During extended periods of no water flow, the water in your chamber can become very hot (Approx. 60 ºC) and potentially lead to scalding. It is

recommended to run your water until this hot water has been purged from your chamber. Do not allow water to contact your skin during this time. To eliminate this condition, a temperature management valve can be installed at the outlet of your UV system.
